Abstract

Recently, many organizations have begun providing
online GNSS (Global Navigation Satellite System)
data processing services. Currently, only one of these organizations
i.e., OPUS (On-line Positioning Users Service)
provides a rapid static data processing option. In case of
static online data processing, the users are required to submit
at least two hours of data to get reasonably precise
results. To provide processing option with less than two
hours of data, NGS (National Geodetic Survey) developed
OPUS–RS for rapid static data processing so that usersmay
submit as little as 15 minutes of dual frequency GNSS data.
In this study, multiple observation sessions are conducted
at the same locations to compare OPUS-RS generated coordinates
among the different sessions to see whether separate
values agree with each other. The results indicate that
with OPUS-RS results the differences in horizontal coordinates
agree with each other within 3.5 cm and vertical coordinates
agree within 7.2 cm. For an independent check,
OPUS-RS results are also compared against LGO(Leica Geo
Office) produced Static results; this comparison yielded
up to 4.5 cm variations among horizontal coordinate differences
and variations among vertical coordinate differences
are up to 11.4 cm.
